After the dust settled from our testing we found out a few things from the AUTO USB. The Strontium AUTO USB does max out USB 2.0 with the read speeds, but the write speeds are slower, coming in at around 7MB/s. The chip on board was not able to be tested as none of our cars our friends cars had USB connections in their cars. If it does work as intended that will just be an added bonus. Another thing to keep in mind, this AUTO USB stick has an MSRP of $10 which is a huge factor in buying flash drives. It is nice and cheap with great read speeds and average write speeds for other flash drives in the price range."
